To all whom, it may concern;

Be it known that 1,;CHARLES .EFRILELa citizen of theUnited States,residing atNewton, in the countyof 'Middlesexland State of 5Massachusetts, have invented anew and use.-

ful Improvementin Conical-Tube Holders for Winding-Machines, of whichthe following isv 'aspecification. 1 i

Referring to the drawings, Figure l isa 1c side viewof myimprovedconical-shell holder,

provided therefor. Upon the cone-shaped 1 .end portion (designated D) iscut or formed .20 a left-hand'spiral threadD. At the opposite endahollowcone shaped'cupE is mounted concentrically on the portion of thearborformed for the purpose near the end 0.. Radialarms'F,-suitably'shaped to be readily V g 5 held bythe fingers, aresecurelyfastened to the arbor A by the pin G. A Wire spring H, slightly incompression, reacts on the arms,

F and the interior end surface of E, thereby i pressing the cone-shapedcup E against the notrin use. -A- sectional viewof a conical'shell' J isshown secured to the holder in Fig. 2with the parts occupying theirrelativevpositions; When in operation, the larger end of the conical.shell, usually madeof compressed paper or pasteboard, is thrust upon theend B of the arbor A until the cone-shaped surface of the hollow cup Ebegins to bear upon 4c the interior of the shellJ, then holding the.

cone stationary in .one hand, grasping the farms E withthefingers of theother .hand, slightly pushin'gth'eholder into the cone, and at the sametimerotating the arborla revolu- 45 tion or part of a revolution to theleft,- or in .the direction of the arrowinFig. 1. The spiral thread-D isforcedint the material of the cone sufficiently to hold the cone thereonv and prevent the same from loosening from 1 5c the arbor when placed inthe machine during the winding process. 'The taper of the end D beingslightly less than'that of the cone-;

Fig. 3 is an'ehdview'of theconinsuring evenn b'ycomp'ression orthe'spring H to a firm and uniform bearing against the interior of the Vshaped cup E allows the latter to be pushed come before the threadedportion D reaches; j a diameter of a cone smallenough to engage'thescrew-threads. .To remove 'the conical shell from its holder," thearbor is rotated to the. right, or in'the direction opposite to thearrow, as shown in Fig. 1. The reaction of .thespring H materiallyaidsthis operation .5

by causing the arbor to be more easily-released from the shell.

This holder by virtue of its construction causes the surfaces ofirregularly-made cones .to assume a perfectly-conical shape, thereby Hessinwindi'ng and maximum production of'yarn.

This device constitutes asimpleand effect,

cone shape and maybe easily and cheaply made. i f

' Having thus described my invention, 1 claimas new and desire to securebyLetters.

Patent,

' '1.-'A shell-holder having anarbor provided with a conicalscrew-threaded end, a springsupported conical cup loose on the arbor, in

her with respect to the cup, as described. 1

2. Ashellholder for winding-machines,

the arbor with respect to the cup, in combination with aspring-supportfor the conical cup, as described.v

3. In a'shell-holder for'windi' ng machines,

the combination with the arbor A, the spiral threads D on thearbor'andfthejradial f arms F, of the cup E and'thespiral spring H,

with the arbor, as described.

In testimohy whereof Ijliave signed my whereby the shell is supportedconcentricname to thisspecification in the presence of,

two subscribing witnesses.
